IMPROVED' LUBRICATOR.

Specification forming part of Letters Patent lill,352, dated March `l1, 1856.

lVhich are in Motion; and I do hereby declare y 'that the following specification, taken in connection with the drawings, is afull, complete, and exact description thereof, reference being had to the drawings making part of this specilieation. l

In the drawings, Figure l is a front .elevation of the apparatus as applied to a crankpin and connecting-rod brasses; and Fig. 2 is a side View thereof, with the iiexible connection shown in section.

The same letters refer lto the same partsin both gures. I f

The difculties attending the lubrication of moving arts of machinery other than mere shafts W ien in rapid motion are well known. Itis necessary either to slow down or decrease the velocity in order to fill the oil-cups properly, or-else to take the chances and pour an intermittent stream of oil, which sometimes hit-s and sometimes misses the cup, while oil is wasted for no purpose, and even worse, as it dirties and gums up those parts on which it falls. These considerations apply with most force when it is attempted'to oil a rapidlyrevolving crank-pin or jaws pf any kind moving on guides which are not vertical.

The object of my invention -is yto remedy these well-known evils, and the nature thereof consists in lubricating a moving rubbing sur- Eiaee by means of a flexible connection, in

combination, with a stationary oil-cup, substantially inthe manner and for the purposes as herein specified.

Iny order to carry out my invention, an oilcup of any ordinary construction is secured upon a proper bracket or otherwise at some convenient spot near .to the surface to be lubricated, and this cup is con nccted by means ol a proper liexible tube with thermoving surface Athrough a hole or passage in that surface, the tube being suiciently iiexible to accommodate itself to the vary ing distances between the surface and the cup, and also tothe varions changes of direction of the tube caused by the motion of the surface relatively to the .oil-cup. There are many varieties of flexible tube which attainv that characteristic, either on account of the material of which they are composed or by means of proper joints applied to tubes of rigid material, which will answer my purpose. A In the drawings is represeifted l'a .iiexible tube which I have used experimentally with success, and it is shown as appliedjto a crankpin embraced by an ordinary connecting-rod,

asv-that is one of the most difficult moving parts to lubricate.

In the drawings the crank-pin is represented at U, with the usual bra'ssesc c surrounding the same. socket H, composed of two pieces, as usual, and inelosing a perforated ball G, to which is attached a tube J, Within which is inclo'sed another tube I, free to slide therein. Atthe part K the outside of the inner tube its tightly againsttheinside of the outer tube, the joint being ground or else` a small stuffing-box being applied there. to a ball B, inclosed in another socket C D,

attached to the bottom 'of an oil-cup A, sup.v i

pbrted upon a bracket b. Twosmall passages T and E connect the lower socket with the surfacesto' be lubricated. and the upper socket with the oil-cup. There is therefore an open tube connecting -theoil-cup with the surfaces.

The oil-cup represented in the drawings is that knownas the"mechanieal oil-cufp, inv

which a ,series of small 'spoons take upsmall quautitiesof oil from a reservoir and drop it into a tube. The passage E connects with the tube, and the oil as lifted by Vthe" spoons. drops or trickles through the balls, tubes,an.d passages onto a' part of the circumference of the crank-pin. t

The tubes must have sucient movement one within the other to compensate for the throw ofl the crank. and it is clear without j description of the operation and from mere inspection of the-drawings that the slide and socket-j ointstogetherwill accom modate themselves to all movementsot'the crank-pin or stub-end of the connecting-rod, even allowing for side vibration which might arise from the crank-pin deviating from its true course o n account ofv the shaft being out of line.

Now it will be obvious that many other flexible connecting-tubes might be used yin Upon the strap c is secured a.l

The tube I is attached like those used for extension gas-burners might replace the sliding tubes, or other changes might be made so long as the tube is sufflcientl flexible and is connected atone end Witht e oil-cup and at the other with the surfaces to be lubricated.

Upon a; small pivot M, attached to the bracket, is mounted a small `lever L, one of whose ends VM embraces the upper tube and rocks with it, while theother end at O is slotted. A rook-shaft S, carrying an arm R, also slotted, givesmotion to the mechanism Within the oil-cup and receives motion from the lever, being connected therewith yby a small bolt, washers, dac., as shown at P. `By mov- Y ing `this bolt up or down after being loosened, land then setting it fast again, the arc through which the rock-shaft. arm vibrates will be varied, and consequently the supply of oil, for when the arm vibrates in a smaller arc a less number of spoonfuls of oil will be delivered in a given number of vibrations. I f the spoons should at any time deliver tooI much oil, so

that the tube-should lill when atits greatest elongation, it is clear that as the tubes *slide within each other to shorten again the oil will be forced -back through the small reservoir into the reservoir from which the spoons dip it up. l

An ordinary oil-cup, or one provided with' a tube and piece of wicking, may be employed in place of the mechanical cup represented in the drawings, but not with'as good eco- Il omioal effect, the difference being just that between different kinds of oil-cup as usually fitted when used without a iexible tube.

As before stated, I have ,shown my apparatus as applied to a crank-pin; but it is ,applicable to .all moving rubbing-surfaces.

l Havingthus described my lubricating ap- '-'paratus, I claim as of my own'invention 1-1. A stationary oil cup or reservoir, in combination with a fiexible tube one of Whose ends communicates with the cup and the other with the surfaces to be lubricated, subherein specified.

2. Giving motion to the spoons of amechanical oil-cup when it is used in combination with-a flexible tube by means of a vibrating lever or its equivalent, which derivesl its motion from the tube itself, substantially] stantiallyin the manuel' and for the purposes asl herein set forth.
